CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2017/1945, filed Aug. 9, 2017, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: ‘TSAECH1709’ is a hybrid seedling selection resulting from the controlled pollination of an unnamed Echeveria pulidonis x Echeveria hybrid ‘Perle von Nurnberg’ hybrid plant (not patented), the seed parent, with an unnamed Echeveria lilacina plant (not patented), the pollen parent. The crossing was made by the inventor in the summer of 2013 at a commercial greenhouse in Heerhugowaard, the Netherlands. In the summer of 2014, one seedling was observed which exhibited unique growth and foliage characteristics. The seedling was isolated for further evaluation in order to confirm the distinctness and stability of the characteristics first observed. Upon confirmation of distinctness and stability, ‘TSAECH1709’ was selected for commercialization.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘TSAECH1709’, by way of rooting leaf cuttings, was first initiated in the summer of 2015 at the inventor's commercial greenhouse in Heerhugowaard, the Netherlands. Through three subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘TSAECH1709’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘TSAECH1709’. These characteristics in combination distinguish ‘TSAECH1709’ as a new and distinct Echeveria hybrid cultivar:

-   -   1. ‘TSAECH1709’ exhibits succulent foliage arranged in a compact         basal rosette; and     -   2. ‘TSAECH1709’ exhibits moderately glaucous foliage; and     -   3. ‘TSAECH1709’ exhibits light greyed-green foliage that is         margined and tipped with pink.

FIG. 4 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the abaxial surface of the mature foliage ‘TSAECH1709’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in February of 2018 describe averages from a sample set of six specimens of 6 months old ‘TSAECH1709’ plants grown in 10 cm nursery containers at commercial greenhouse in Heerhugowaard, the Netherlands. Plants were produced using conventional greenhouse production protocols for Echeveria plants which consisted of minimal irrigation and fertilizer applications, and chemical pest and disease control measures against mealy bug and Botrytis as required. Plants were grown under approximately 50 percent shade after propagation and later exposed to full sun once they began to mature. No photoperiodic treatments or artificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘TSAECH1709’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).

A botanical description of ‘TSAECH1709’ and comparisons with the parent plants and closest known comparator are provided below.
